—The medium-access control (MAC) protocol is one of the key components in wireless local area networks (WLANs). The main features of a MAC protocol are high throughput, good fairness, energy efficiency, and support priority guarantees, especially under distributed contention-based environment. Based on the current standardized IEEE 802.11 distributed(More)
—This paper studies multihop optical networks in which nodes employ wavelength routing switches that enable the establishment of wavelength division multiplexed (WDM) channels , called lightpaths, between node pairs. In fact, most optical networks are multifiber networks. The problem of dynamical routing and assignment of wavelength (RAW) in such networks(More)
In this paper, we investigate the protection design for survivable meshed WDM optical networks, and propose a novel heuristic algorithm, which is called segment shared protection (SSP), to completely protect the dual-link failures. For each connection request, first SSP computes a least-cost working path, second SSP divides the working path into several(More)
